- Q: who knows the fire resistant levels of fireproofing glass?
- Fireproofing glass is a kind of special glass which can keep its integrity in the regular fire resistance test, and it can be divided into three classes: fireproofing glass,fireproofing glass A class is a kind of fireproofing glass that can satisfy the requirements of refractory integrity, fire resistance and thermal insulation. Including composite flameproof?glass and perfusion type fireproofing glass . This kind of glass has the properiyies of transmittance, fireproofing ( smoke insulation, fireproofing, and keeping out thermal radiation), sound insulation, shock resistance, and it's suitable for steel and wooden fire door of building decoration, windows, varnishing, partition walldaylighting?roof,ceiling?screen,perspective floor and other construction components demading for transparency and fireproofing. Class B, it's a kind of fireproofing glass that can satisfy the requirements of refractory integrity, refractory and thermal insulation at the same time. Such kind of fireproofing glasses mostly are composite fireproofing glasses and has characteristics of transmittance,fireproofing and smoke insulation. Class C, it's a kind of monolithic fireproofing glass that only satisfies the requirements of refractory integrity. This kind of glass has characteristics of transmittance, fireproofing, smoke insulation and high strength,etc. It's suitable for fireproofing glass partition wall, fire Windows, outside curtain wall and other places without insulation requirements. hope it can help you.
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- Setting the acid resistancere of fractory products is simple; R22, two measurement methods are both bricking refractory products, using the mass fraction of the original dry to indicate. It is generally select vitriol as the medium of erosion, such as the international standard determination of the resistance to sulfate of dense shaped refractory products "(ISO8890) and PRE /, grinding fine particles to 0.63 ~ 0.80 mm, and then measure its quality loss, put it in the vitriol with mass fraction of 70%, finally boil 6 h.
- Q: Which industry does refractory belong to?
- It belongs to construction industry.
- Q: which kind of material should be used in fireproofing cabinet?
- Here are a few good materials: 1. The mineral wool board, glass wool board: it mainly tales mineral wool, glass wool as insulation materials. It's non-combustible, light weight and has good high temperature resistance, but there are shortcomings ① short?fiber will harm the human respiratory system, ② poor sheet strength, ③ poor barrier property of sheet for smoke of fire disaster, ④ poor decorative properity, ⑤large installment and construction work. Thus, most of the boards were sheets that take inorganic anchoring material as base material, glass wool as reinforcing material. 2. cement board: Cement board has high strength and wide sources. It is often used in fireproof suspended?ceiling and partition in the past, but it has poor fire resistance and is easy to burst and lose protective function , which will limit it's applications. Cement concrete component has good thermal insulation and sound insulation properties, and it can be used as partition and roof board. Fiber reinforced cement board and other improved varieties appear in the construction?materials market, and they are high strength and have good fire resistance, but their disadvantages are poor toughness, large alkalinity and poor decoration effect. 3. perlite board, cenosphere board, vermiculite board: It's a kind of hollow plate that takes low alkalinity cement as base material, perlite, glass beads, vermiculite as the aerated filling material, and is made by adding some auxiliary. It has characteristics of light weight, high strength, good toughness, fireproofing and thermal insulation, easy for construction,etc. and it can be widely used in high-rise building frame compartment, household, bathroom, kitchen, communication pipe and other non-load bearing areas.
- Q: What's the refractory material in common use currently?
- (1) Alumina-silica refractory brick: Except the transition band, hot end and firing zone of the rotatory cement kiln, it can be applied to the whole burning system of the precalcining kiln, such as the fixed wall lining, wicket, cooling machine, tertiary air duct, burner, etc. It mainly includes alkali-resisting brick, high alumina (anti stripping) brick, silica-mullite brick, etc. (2) Basic refractory: For the upper transition band close to the part of burning zone and the burning zone, its inner lining can endure the highest flame temperature of 2000℃ and material temperature of 1350℃-1400℃, and it also has to withstand the permeation of sulfur and alkali compounds, permeation, thermal shock and oxidoreduction of hot-melt clinkers (liquid phase), mechanical stress of elliptic cylinder deformation, etc. Therefore, inner linings are the most demanding parts to withstand stress, and only basic refractory can meet with requirements under this working condition. (3) Fireclay insulating refractory: Its microstructure has notable characteristics of high porosity, large pore size and thermal insulation performance. For its low volume density and light weight, it is usually referred to as lightweight refractory. Fireclay insulating refractory product has great varieties, and it is usually classified and named according to its chemical and mineral compositions or production raw materials, and it is also classified according to its operating temperature and material form. Currently, the most used main thermal insulation material for the precalciner kiln system at home and abroad is calcium silicate board; besides, light weight castable and insulating fire brick are increasingly used year by year. Other thermal insulation materials are mainly ceramic fiber products.
- Q: What kind of material is refractory bauxite?
- Refractory bauxite, also known as bauxite alumina or bauxite with high alumina, is the main raw material for the production of high alumina (aluminum content ≥48%, belongs to LAS) refractory.
- Q: What does refractory mean?
- Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..Special materials often use AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so onUnshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..
- Q: What are the main characteristics of the sic refractories?
- 1. The usage temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand dramatic changes in temperature, and a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
- Q: what needs to be noted when choosing and using blast furnace fireproof materials?
- it depends on the size of the blast furnace. below 200 cubic meters alumina bricks and carbon brickcan be used. 200 cubic meters and above are currently integrated bottom, not the same as the size of the cubic level, varying in the use of refactory. I hope my answers above are helpful to you and your ideal anwers.
- Q: How do refractory materials apply into pyrophyllite?
- Generally speaking, shaped refractory materials require of some powdery materials like spray grouts and iron trough in addition to pyrophyllite brick made of a mixture of pyrophyllite aggregate and powers.
